Bridge components required for U snRNA export, the cap binding complex (CBC)-bound snRNA on the one hand and the GTPase Ran in its active GTP-bound form together with the export receptor XPO1 on the other. Its phosphorylation in the nucleus is required for U snRNA export complex assembly and export, while its dephosphorylation in the cytoplasm causes export complex disassembly. It is recycled back to the nucleus via the importin alpha/beta heterodimeric import receptor. The directionality of nuclear export is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus. Its compartmentalized phosphorylation cycle may also contribute to the directionality of export. Binds strongly to m7G-capped U1 and U5 small nuclear RNAs (snRNAs) in a sequence-unspecific manner and phosphorylation- independent manner (By similarity). Plays also a role in the biogenesis of U3 small nucleolar RNA (snoRNA). Involved in the U3 snoRNA transport from nucleoplasm to Cajal bodies. Binds strongly to m7G-capped U3, U8 and U13 precursor snoRNAs and weakly to trimethylated (TMG)-capped U3, U8 and U13 snoRNAs. Binds also to telomerase RNA. {ECO:0000250, ECO:0000269|PubMed:15574332, ECO:0000269|PubMed:15574333}. |RNA GG bind| |snRNA export from nucleus| |snRNA transport| |toxic substance binding| |ncRNA export from nucleus| |Cajal body| |snRNA transcription by RNA polymerase II| |snRNA transcription| |ncRNA transcription| |RNA export from nucleus| |nuclear export| |nucleic acid transport| |RNA transport| |establishment of RNA localization| |RNA localization| |nucleobase-containing compound transport| |nucleocytoplasmic transport| |nuclear transport| |neuronal cell body| |transcription by RNA polymerase II| |centrosome| |transcription, DNA-templated| |nucleic acid-templated transcription| |RNA biosynthetic process| |nucleobase-containing compound biosynthetic process| |heterocycle biosynthetic process| |aromatic compound biosynthetic process| |organic cyclic compound biosynthetic process| |RNA binding| |protein transport| |intracellular transport| |peptide transport| |amide transport| |establishment of protein localization| |cellular nitrogen compound biosynthetic process| |RNA metabolic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| |establishment of localization in cell| |nitrogen compound transport| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp346|CoCl2 18μM R07 exp346]]|-2.17| |[[:results:exp35|TRAIL 5ng/ml R00 exp35]]|-2.06| |[[:results:exp60|Vinblastine 0.002μM R01 exp60]]|-1.95| |[[:results:exp52|Ribavirin 10μM R01 exp52]]|-1.94| |[[:results:exp75|MK-1775 0.32μM R02 exp75]]|-1.81| |[[:results:exp160|Ribavirin 10 to 15μM on day4 R04 exp160]]|-1.71| |[[:results:exp152|SGC2043 10μM R03 exp152]]|1.81| |[[:results:exp237|NN-Diethyl-meta-toluamide 100μM R05 exp237]]|2.2| No correlation found to any other genes in chemogenomics.
